Understand more about how rain and humidity connected and affected. So, it will be easy for you to control humidity within your work environment. ABSOLUTE HUMIDITY: Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature.

The higher the amount of water vapor, the higher the absolute humidity. For example, a maximum of about 30 grams of water vapor can. 70° Fahrenheit and 50% Relative Humidity (RH) is an ideal environment for book storage         Hot, dry conditions lead to brittle paper and leather         Damp storage conditions lead to mold growth Store books in an area with a fairly consistent temperature and relative humidity.
